Problems solved by technology

This negative effect is often even more pronounced when the above mentioned pressure ratios on the compressor elements are higher and can lead to undesired damage
[0015] The risk of undesired damage is even greater when there is no elastic coupling between the drive and compressor elements

Embodiment Construction

[0061] figure 1 The shown device relates to a compressor according to the invention, in this case a fluid-injected screw compressor 1 comprising a conventional screw compressor element 2 with a housing 3 in which The two cooperating helical rotors 4 are driven by motors not shown in the figures or the like.

[0062] The compressor element 2 is characterized by an inlet 5, which is sealable by a controllable inlet valve 6 with a valved inlet 7, which is connected by a suction line 8 to an inlet filter 9 for sucking gas from the environment, in this case Below is air.

[0063] The compressor element 2 is also equipped with an outlet 10 to which a pressure line 11 is connected, via a pressure tank 12 containing a fluid separator 13 and via a cooler 14 with downstream for supplying various pneumatic tools or the like ( Not shown here) user network 15 connection.

[0064] In this case, a non-return valve 16 is arranged at the outlet 10 of the compressor element 2 and a minimum p...

Abstract

The invention relates to a method for controlling a compressor towards a no-load condition, wherein the compressor comprises a compressor element (2) with an inlet (5), in which a residual flow (Q D ) is drawn towards and into the compressor element (2) via the inlet (5), and for a transition from a loaded state of the compressor to an unloaded state, the compressor element (2) The inlet (5) of is partially closed in successive discrete transition steps.

Description

technical field [0001] The present invention relates to a compressor, and in particular to a method for controlling such a compressor during a transition from a load state to an unload state in which the compressor must provide a network of users with compression Gas, such as pressurized air, does not consume compressed gas in said no-load condition. [0002] The invention more particularly relates to a method for controlling a compressor towards a no-load condition, the compressor comprising a compressor element having an inlet and an inlet valve, wherein in the no-load condition a residual flow is directed towards the compressor element via the inlet is drawn into and drawn into the compressor element and is discharged via the discharge valve to the outlet of the compressor, and wherein, for the transition of the compressor from a loaded state to an unloaded state, the inlet of the compressor element is at successive discrete Partially closed during the transition step.
